Which of the following atoms and ions is (are) isoelectronic with S2+ ?
Transcribed Image Text:### Which of the following atoms and ions is (are) isoelectronic with S²⁺?
**Options:**
- **A. As³⁺**
- **B. Ar**
- **C. Cl³⁺**
- **D. Si⁴⁺**
### Detailed Explanation:
In chemistry, isoelectronic species are atoms and ions that have the same number of electrons. Given the ion S²⁺, we need to determine which of the given options is isoelectronic with it.
**Steps to Determine Isoelectronic Species:**
1. **Determine the number of electrons in S²⁺:**
- Sulfur (S) has an atomic number of 16, meaning a neutral sulfur atom has 16 electrons.
- S²⁺ indicates that the sulfur atom has lost 2 electrons.
- Therefore, S²⁺ has 16 - 2 = 14 electrons.
2. **Evaluate each option to find its electron count:**
- **A. As³⁺:**
- Arsenic (As) has an atomic number of 33.
- As³⁺ indicates a loss of 3 electrons.
- Therefore, As³⁺ has 33 - 3 = 30 electrons. (Not isoelectronic with S²⁺)
- **B. Ar:**
- Argon (Ar) has an atomic number of 18.
- Argon is a noble gas and is neutral, so it has 18 electrons. (Not isoelectronic with S²⁺)
- **C. Cl³⁺:**
- Chlorine (Cl) has an atomic number of 17.
- Cl³⁺ indicates a loss of 3 electrons.
- Therefore, Cl³⁺ has 17 - 3 = 14 electrons. (Isoelectronic with S²⁺)
- **D. Si⁴⁺:**
- Silicon (Si) has an atomic number of 14.
- Si⁴⁺ indicates a loss of 4 electrons.
- Therefore, Si⁴⁺ has 14 - 4 = 10 electrons. (Not isoelectronic with S²⁺)
### Conclusion:
From the given options, **C. Cl³⁺** is isoelectronic
